Title: X-ray image-pickup device and x-ray diagnostic apparatus
Inventor: TANAKA MANABU
IPC: H01L31/09
Filed: 1998-02-04
Abstract: PROBLEM TO BE SOLVED: To enable realtime X-ray dynamic image fluoroscopy with short reset time by raising the numerical aperture of each X-ray detecting pixel, and enhancing the sensitivity in detection by X-ray. SOLUTION: In a direct conversion system of X-ray image-pick device 109, when the voltage of pixels is increased to a specified voltage by the charge converted into a charge from X-ray and accumulated in pixels, the charge is discharged out of the pixels. Then, a film diode (TFT), for example, MIM (metal-insulator-metal) structure, MSI(metal-semi-insulator) structure, BTB(back- to-back, reverse series) structure, or the like being a two-terminal element which shows a nonlinear resistance property and is made by a film is used. Hereby, a protective diode can be made with an in-pixel space factor smaller than the protective diode by TFT, so that the numerical aperture and CST can be secured more than at the time of TFT, and an X-ray image-pick device 109 high in detection sensitivity and S/N ratio can be made.

Title: Detection of defect in weld zone
Inventor: SAKAI YOSHIYA
IPC: B23K31/00
Filed: 1983-02-15
Abstract: PURPOSE:To detect surely all the welding defects of >=0.1mm.phi by drawing a seam welded wire with a die so as to have <=2mum average surface roughness then subjecting the same to an eddy current flaw detection with >=5kHz high frequency current. CONSTITUTION:A flux F is filled in a sleeve pipe 1 of a wire, and a flaw detector is disposed near the wire and current is conducted to the coil of the flaw detector in order to subject this wire to an eddy current flaw detection. The wire is drawn with a die which is the 1st means so as to have <=2mum outside surface roughenss and the frequency of the detecting current of the flaw detector is set at >=kHz. The detecting noise arising from the roughened inside and outside surfaces of the sleeve steel of the wire is thus suppressed and all the welding defects of >=0.1mm.phi are surely detected.

Title: Mechanism for locating pin or the like
Inventor: YANAGIHARA KAZUO
IPC: F16B1/02
Filed: 1980-02-27
Abstract: PURPOSE: To permit a pin or the like to be stopped at a predetermined position with a simple operation by enabling a lock pin fitted into a through hole of a spring- urged slidable ring to be inserted into peripheral grooves formed respectively in the inner periphery of a guide tube and the outer periphery of the pin.  
     CONSTITUTION: As an operating string 10 is pulled to make a lock pin 7 approach a V-groove 4b of a guide tube 4, a ring 6 is urged right by a spring 8 so that the spherical surface of the lock pin 7 is urged against a slant surface of the V-shaped groove 1b and coincides with the V-shaped groove 4b to move the lock pin 7 to the outer peripheral direction to fit into the V-shaped groove 4b. Thus, the ring 6 is click-fixed to the guide tube 4. Then, the inner periphery of the ring 6 and the outer periphery 1a of the head of the pin 1 can easily slide to move only the pin 1 leftward by the expanding force of the spring 8 so that a flange 1c abuts against the shoulder of the pin hole to permit the pin 1 to be completely inserted and stopped.

Title: Copying machine provided with punch mechanism
Inventor: TAKANO TSUTOMU
IPC: G03G15/00
Filed: 1982-02-16
Abstract: PURPOSE:To automatically punch holes for binding copies through a copied paper sheet in a copying machine after copying, and discharge it, by providing a stopper for blocking a paper conveying route near the outlet of a puncher, and allowing a paper sheet to form a loop during the stop of conveyance, when the forward end of the sheet contacts with the stopper and its conveyance is hindered. CONSTITUTION:When a copied paper sheet 10 is conveyed from the left side with conveying rolls 5, 6, and the forward end of the sheet 10 passes by a photosensor 7, a solenoid 2 is actuated with this signal to protrude a stopper 4 from the underside of a conveyance route, and thus, conveyance of the sheet 10 is stopped. At the same tme, a clutch 3 is disconnected with the signal of the photosensor 7 to stop the roll 6. When the sheet is stopped, a punching drill is lowered by actuating a solenoid 1 to punch holes. Pieces of paper cut drop in a receiving box 8. The roll 6 stops while conveyance of the sheet 10 is suspended, but the roll 5 continues to rotate, so the sheet 10 is allowed to form a loop to escape the feed of the sheet 10. After punching, the solenoids 1, 2 are deenergized, and the clutch 3 is connected to convey the sheet 10 to the right side and discharge it.

Title: Recombiner
Inventor: TAKAHASHI MASATO
IPC: B01J8/04
Filed: 1988-02-05
Abstract: PURPOSE:To prevent soaring up and rolling of catalysts by forming a catalyst layer in a recombination container and providing in-net carriers formed by housing the carriers into stainless steel nets on said catalyst layer. CONSTITUTION:This recombiner 8 is constituted by forming the catalyst layer 13 in the recombination container 12 and providing the in-net carriers 20 to a laminar state on the catalyst layer 13. The off-gas entering the recombination container 12 from a gas inlet 14 collides first against the in-net carriers 20 and the flow of the off-gas A is regulated by the carriers 20. Since the carriers 20 are formed by housing alumina 24 of a granular, pellet or other state into the stainless steel nets 23, the carriers are not moved by the flow of the off-gas A. The soaring up and rolling of the catalysts are, therefore, prevented and the deviation of the catalysts in the container 12 and the dislodgment of palladium from the surface of the alumina 24 are prevented.

Title: Bubble generating liquid pump
Inventor: KUROSAKI YOSHINORI
IPC: F04B53/10
Filed: 1982-02-17
Abstract: PURPOSE:To prevent an occurrence of gas lock and to transfer the liquid normally by opening individual valves with buoyancy at the suction and discharge sides in the processed liquid so as to discharge bubbles outside a pump immediately when the bubbles generated from the processed liquid are accumulated in the pump. CONSTITUTION:Bubbles generated from the processed liquid in a casing inner hull 2 and a discharge pipe 22 rise through the liquid respectively to form a bubble layer below individual valve bodies 11, 14 at the suction and discharge sides, then the valve bodies 11, 14 lose buoyancy respectively by means of this bubble layer and are slightly lowered and opened, the bubble layer rises through the liquid and the opened valves, and the bubbles passing through a check valve 3 at the suction side are discharged into the atmosphere through a gas vent pipe 21. Since this bubble discharge action is performed automatically at all times, no bubble is accumulated in the casing inner hull 2 and valve chests 9, 12, thus preventing an occurrence of gas lock and allowing the normal suction and discharge continuously.
